Prefix indicating related to tissue?

• A. Histo/o
• B. Lingu/o
• C. Onc/o
• D. Dips/o

Answer: (A)

Histo- is the combining form that means tissue. It comes from a Greek word for tissue and is used in terms like histology (the study of tissues) and histopathology (disease of tissues), showing its clear link to tissue. The other forms point to other concepts: lingu- refers to the tongue, onc- to tumors, and dips- to thirst. So histo- is the correct choice for “related to tissue.”
